Disclosed herein is a voltage sensing assembly including sensing bus bars connected to series connection portions of battery cells for sensing the voltage of the battery cells, a printed circuit board (PCB), to the upper part of which the sensing bus bars are and to the lower part of which a connector is coupled, the connector mounted on the PCB, an insulative mounting member including a receiving part having a shape corresponding to the shape of the PCB such that the PCB is mounted in the receiving part, the receiving part being provided at one side thereof with openings, through which the sensing bus bars extend, and an insulation sheet attached to the front surface of the PCB.

Voltage sensing assembly and battery module including the same

Disclosed herein is a battery cell including a battery cell body having an electrode assembly mounted in a cell case, an electrode terminal protruding from at least one end of the battery cell body, and a connection protrusion for voltage sensing formed integrally with the electrode terminal.

Battery cell having connecting protrusion for voltage sensing and battery module comprising the same

A battery cell is provided. The battery cell includes a battery case, an electrode assembly located in the battery case, the electrode assembly comprising a cathode, an anode, and a separator disposed between the cathode and the anode, an electrolyte present in the battery case, the battery case being sealed at a perimeter thereof, and a frame coupled to the perimeter of the battery case, the frame having a venting guiding portion at the perimeter of the battery case, such that sealing of the battery case is released through the venting guiding portion when internal pressure of the battery cell increases, the venting guiding portion comprising a reduction in the amount of material of the frame in a predetermined location at the perimeter of the battery case. A battery cell module is also provided.

Battery module having venting guiding portion

Disclosed herein is a battery module including two or more battery cells, which can be charged and discharged, arranged in a stacked state and cartridges for fixing the battery cells to constitute a battery cell stack, wherein each of the cartridges includes a cooling fin contacting the battery cells and a cartridge frame for fixing the cooling fin, the cooling fin includes two cooling plates, the cooling plates being mounted to the cartridge frame in a state of being spaced apart from each other in order to define a coolant flow channel, the cartridge frame is provided with openings communicating with the coolant flow channel defined between the cooling plates, and one side or opposite sides of each of the battery cells are sealed by a sealing member on an interface between each of the battery cells and the coolant flow channel in order to prevent gases generated in the battery cells from being introduced into the coolant flow channel.

Battery module having structure for preventing mixing of coolant and vent gas

Disclosed herein is a battery module including a battery cell array including two or more stacked battery cells, each of which is configured to have a structure in which an electrode assembly, including a cathode, an anode, and a separator disposed between the cathode and the anode, is received in a battery case together with an electrolyte in a sealed state, and fixing members, each of which is integrally coupled to a portion or the entirety of an outer edge of a corresponding one of the battery cells, each of the fixing members being provided with an assembly type coupling structure, by which the fixing members are coupled to each other such that the battery cell array forms a stable stack structure.

Battery module having assembly coupling structure

Disclosed herein is a prismatic battery cell including a pouch-shaped battery cell having an electrode assembly mounted in a pouch-shaped battery case, a cell case, in which the pouch-shaped battery cell is mounted, the cell case having a polyhedral shape, and a terminal case including external input and output terminals, to which electrode terminals of the pouch-shaped battery cell are coupled, the terminal case being coupled to one end of the cell case, the terminal case having a polyhedral shape.
